Kristin Cavallari may be a new mom in the future -- at least that's what she's saying ... 'cause her boyfriend wants to have kids.<br />The reality star explained on her "Let's Be Honest" podcast that her 24-year-old BF, Mark Estes, has his sights set on being a dad -- and because of this, she's been mulling over potentially popping out another baby with him, assuming everything works out.<br />So far it looks like Kristin -- who's currently 37 herself -- might be leaning towards expanding her brood ... even joking with her cohost her future little one could become so famous it'd be her one-way ticket into retirement ... 'cause the kid would be so freaking good looking.<br />Jokes aside, KC is giving it some serious thought ... saying her 3 other kiddos -- Camden, 11, Jaxon, 9, and Saylor, 8 -- are old enough to help out with a new baby. BTW, she shares those three children with her ex-husband, Jay Cutler.<br />Kristin admits she still hasn't figured out if Mark's the one, even though their romance has been on a good track since February.<br />Kristin recently posted a pic of Mark having a chat with one of her kids, so on its face -- she seems to think he's already showing fatherly qualities ... which might be why she's even talking about this.<br />KC has looked head over heels ever since ... and now, parenthood might be on the horizon (again).
